Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Bifunctional enzyme that catalyzes two sequential steps of the aromatic amino acids biosynthetic pathway. The first reaction is catalyzed by the 3-dehydroquinate dehydratase, coded by the aroD domain; the second reaction is catalyzed by the shikimate 5-dehydrogenase, coded by the aroE domain.
Catalytic activity	3-dehydroquinate = 3-dehydroshikimate + H(2)O. Shikimate + NADP(+) = 3-dehydroshikimate + NADPH.
Pathway	Metabolic intermediate biosynthesis; chorismate biosynthesis; chorismate from D-erythrose 4-phosphate and PEP: step 3/7. Metabolic intermediate biosynthesis; chorismate biosynthesis; chorismate from D-erythrose 4-phosphate and PEP: step 4/7.
Sequence similarities	In the N-terminal section; belongs to the type-I 3-dehydroquinase family. In the C-terminal section; belongs to the shikimate dehydrogenase family.
